WEET-REPLENISHING PICK-ANDLPVIOK LOOM.

Application filed March 28, 1925.` Serial No. 19,7130.

rIhis invention relates toy a 'weft replenvisliingY loom of the type in which a plurality ol shuttleboxes are provided on each end oit`V the loom and in which the picking mechanismis so constructed that a Shuttle may be picked from either side 4oi the loom on` any desired pick. This type of loom is used largely in the weaving of fine fabrics in which the pattern may call for the insertion Oi' av single pick of a certain kind or color or illiii'g. ln'sucli looms,I it is common .to use Y more shuttles than therejare boxes at either side of the loom. Consequently the shuttles are shifted about from one box toanoiihor during the operation of the loom, same shuttle may at different timesoccupy any one o i' the different boxes on either side of the loom. Y It is the object of my invention to provide a lconstruction by which a weit carrier of the corresponding V in a substantially less of the particular occupy..

To the attainment oi" this object, I provide a detector for indicating'the exhaust-ion of filling, located at. the drop. box side of the Vloom and remote from the magazine. I also provide a color indicator or releasing device for the magazine which is so `controlled that it will always correspond to the kind or color of wert in tlie running. shuttle,

exhausted shuttle, regardb'ox which said shuttles regardless of the position of said Shuttle in the shuttle boxes.

To the attainment of this general object, l provide many novel features of construction and vI particularly provide. a set of' indi# eating blocks, each block representing a particular shuttle land being moved to correspond with the Vposition and movementof the shuttle in the boxes. The blocks preferably receive their mot-ion. direct -rom the drop box patternchain, so that `they may be vpositioned in advance of the corresponding movements oi the drop boxes.

Many other features o'li'my invention will be hereinafter describedand more particularly pointed out in the appended claims.

Briefly describen, my improved loom comprises a set of the usual vertically' movable drop boxes at one side of the loom and a second set of horizontally shifting shuttle boxes at the opposite or magazine si le of the loom, which latter boxes may be of any desired type and which are shown herein as of the` type disclosed in the prior patent to Eccles, No. 7,137, issued March 5', 1850. The boxes are controlled from a dobby head which is in general of a usual and well known type.

The weft detector is mounted at the drop box side Vof the loom a-ndis so connected to the pattern mechanism that it will always Vco-operate with the running shuttle. I have also connected the weft detector so that it will render the picking mechanism, the dobby and the box motion which it controls, and the take-up all inoperative upon indication of weft exhaustion.

The magazine for my impoved loom is of special` construction as to certain features and I have provided a special indicating mechanism therefor, by whichthe color slide or color indicator of the magazine will always correspond in positionto the kind or color of weft in the running shuttle, regardless of the particular shuttle box in which said shuttle is located at any given time.

By the co-oporation of these several devices, weft exhaustion will be indicated in a,

shuttle at the drop box side of the loom and the exhausted weft carrier will be replaced immediately after the shuttle reaches the magazine side of the loom and regardless of the particularshuttle box in which it may be located at either side of the loom.

Having described the general construction and oper: n of my improved loom, I will nowdcseribe the specific structure of the different' mechanisms which co-operate to produce the results above uetforth.

Detect/ag mec/rameau.

I will first describe the mechanism for detecting the exhaustion of filling in the running shuttle. For this purpose l provide a detector stand 30 (Figs. 2 and which the stand downward against the pressure of the spring 37. The mechanism for pulling `the cord 33 downward is substantially similar to that shown in the prior patent to Ryon, No. 1,205,792, issued November 21, 1916.

Brieflyrdescribcd, this mechanism Vconiprises a lever 40 mounted on a movable pivot 41 24 and 26) and engaging one v the usnal vibrator levers 42 (Fig. pivot 41 is on a second lever 40fFL mounterVY on a ii-xed pivot 41a and engaging a second vibrator lever.

The vibrator levers 42 are selectively poisitioned by pattern rolls 420 (F lgs.

and 2G) mounted on the usual pattern chain 421, periodic-ally advanced by an intermittently actuated driving cylinder 422, or` the vibrator levers may be positioned by other suitable pattern mechanism, such mechanism being the usual commercial structure for controlling the drop boxes for a pick and pick loom and in itself forming no part of my present invention.

ico

, he lever 40 is connected by a link 43 to 46 (Fig. l) connected thereto.

a lever 44 pivoted at 45 and having a cord it its lower y end, the cord 46 is connected to one arm of bell crank 47, and the cord 38 previously described is connected to the second arm of the bell crank 47. l f I The cord 38 passes around a guide pulley 48 (Fig. 2) mounted on the pivot of a swinging arm or lever 49. The cord 3S is then passed around a second guide pulley 50 on the swinging end of the lever 49 and from the pulley 50 passes directly into the tube 3 The lever 49 is connected by a link 5l to' the lifter rod 52 which supportsthc drop boxes on the lay 54. The lever 49jthus rises and falls with the drop boxes 53, maintaining the detector stand 3()y aligned with a given shuttle bex 53 as the latter moves upward or downward. yVhen a change is called for in the position of the shuttle boxes, theA detecting device is moved up or down on the tube 31 in accordance with the movements of the vibrator' levers 42, this change being` made as soon as thepattern chain is drop boxesA have advanced and before the been shifted. For a. more detailed description of the mechanism for aligning the weft detector with the running shuttle box, refer- '64 and the parts operated thereby.

ing mechanism .suitable 'toi-my purposes are shown in Figs. 7 and 8. mounted in a guideway in the stand 3() and is provided at its rear end' with a pivoted detecting member 57 having a forwardly projecting arm 5S. The arm 58 engages the rear portion of a plate which is movably mounted on the slide 56 and which is normally held in the rearward position indicated in Fig. 7 bye spring'GO', which causes a shoulder 61 on the Yplate 59 to engagea pin 62 on the slide 5 ii/'lien the detecting member 57 engages ay bebbin having'a su'flicient amount of weft' thereon, the parts will kbe moved directly forward and no'indicationof weft exhaustion will `be given. substantially exhausted,` the member 57y will slide along the bobbin B, as indicatedl in Fig. 8, swin ing the plate 59 about the'stud 62 and causing the recessed front end 63 of the plate 59 to engage a rod 64 (Figs, 2

and extending'vertically adjacent theV detecting mechanism andA secured at its opposite ends in a traine 65 swinging about' a iied pin 66. A shoulder at the rear vend of the plate 59 is tliusvpositioned in the path oiE a projection 6421 carried by the lay and the plate is torced Vforward thereby. l

A 'second arm GSL'is secured toV shaft 69' and is connected by link 70 to a swinging support 71 which iiorinally'liolds av latch' 72 on theV lay 511 in raised position, as indicated in Fig, 2. A torsion coil spring 73 en' the slia'tt 69 presses the arm 68 yieldingly against the arm 67 and the latter en-v stand 66a to maintain the parts lin the position shown iny Figs. 5, 7, and 25. One end ot said spring 73 issecuredto arm 68 and the other end to bearing 69El in `trame L.

Upon indication oit wett exhaustion, the traine 65 and arm 67 are moved by the projection 64a to the position indicated in dotted'liiies in Fig. S, rocking the arm 68 and shaft 69 'andpermitting the latch 72 to move downward into alignment with' the head 74 oi". a spring pressed sliding rod-75 The detailsof one form et weft detecte' A slide 56 isl lliit when'tlie wett is ot bobbins ror wett carriers. ot each color are heldin their respective (Fig. 2)'. lVhenv this rod is moved rearward an arm 76 ot a collar (7 onv the rod engages astiid 78 ina bell crank 79 pivoted 'e at 8() tothe -looni traine. `The rearwai'dlyv projectingarm 81 oil the bell crank 79 is connected by a cord 82 (Fig. 1) to the upper end of a lever 83 mounted. on a fixed pivot S11 and having adepending por# tion 85v engaging a collar 86 slidable on the picking shaft 87- The collar 86 is connected by links 88 to pick arms S9, said links being reversely connected to the arms so that movement of the collar in the direction ot the arrow a in Fig.` 1 will withdraw the pickrolls 90 from operative position. f

I will now describe the magazine and the horizontally shitting shuttle box mecha# nism associated therewith, which is best Shown in FSS- r9 and 13. IY have shown 111V improved loom as provided .with -loiir shut-- Ltle boxes at each end of the lay and I have. `shown the magazine as arranged for the storage, and release of seven different colors The bobbins vertical compartments by a pair of oppositely -slidingplates or supports 1O2`K(Figs. 11 and 12) of the'typ'e tiilly shown and described in 'the prior patent to Ryoii No. 1,095,321, issued October y10, 16911.

Shuttle indicating finec/zrazz/[singV I will now describe the no-Yel fh-wiiees by whichA I indicate the positionsv of the (filierent shuttles in the drop boxes at thetu'o ends of the lay and by which. 1 eo-ordinate the movements and positions of the magi.- zine litter arms 10G (FiOj. 11) with the changing positions et the different sl'iutthes.V For this purpose provide a frameor support (Fig. 1(5) on which a pair of ola/tes or supports 151 and 152 are mounted :tor yertical slidingmove-ment. Each support 151 or 152 is provided with a ot horizontal .p recesses 154 (Fig. 19) in which a series o"I indicating' blocks 155 freely n'1o;fable. The blocks 155 are held from displacement by cover' plates 156.

Each block 155 (Fig. 21) is provided With a lug or projection 157 on its outer taee and these projections vary in height. each block having a projection of dillerent height and each. block being assigned to represent a particular shuttle in the loom.. Each of the indicating bloelts 155 is provided with a notch 1Y0 (Fig. 21) in its rear face, adapted to be engaged by a springl pressed plunger 171 (Fig. 19), so that it will be yieldingly retained in its recess 154.

llt)

- eenige-11l movement, the supports 151 and 152 are con-v nected to rods or links 158 and 159 (Fig. 1'),

link 159 for support 152 being connected at its upper end to the indicating lever 44 previously described. The rod 158 for support 151 is connected to a second indicatorr V- lever 161. Springs 160 are connected tothe v 2oy rods 158 and159 and lower the samewhen permitted to do so by levers 44 and` 161. Each of these levers is positioned by a compound lever 40p-40 controlled by two vibratornlevers 42, as previously'explained and as more fully shown and described in the' n p the hook 17 8 and the plunger 172 is thereby prior patent toLRyon, No. 1,205,792.

By this construction, the supports 151 and 152 are shifted vertically to correspond to the movements ofthe boxes and aremoved to their new'positions as soon as a change in the boxes is indicated and lbefore the change actually takes place. A y

A pair of plungers 172 and 173 (Fig. 14) are mounted-inbearings in the frame 150 andare positioned to engage a block 155 'corresponding to the running shuttle,r` moving the block from one side to the other in accordance with the movementsv of `the The plungers 172`and173 are actuated by levers 174 and 175 and are yieldingly withdrawn by springs 176. The lever-"174 hasa hook 177 movable into and out of engaging position with ar hook 178 on the lower end of an actuating lever v180. The lever 175 has a corresponding hook 181 movable intoA and out of engagement with a hook 182 pivoted tothe upper part of the actuatl ing lever 180. Levers 174'and 175 areprovided with stop screws 174 and 175 which engageframe 150 to limit outward movement ofthe plungers. 7 Y

The lever 180 is connected by a llink 183v to an arm 184'which engages a cam 185 on the dobby driveV shaft 99 previously described.V The cam V1-85 makes one revolution' for each revolution of the picking shaft 87 and through theconnections described causes the blocks 155 to Vduplicate the movement of the active shuttle. Spring 1841 holds the arm 184 against cam 185 and the latter is so formed as to move the hooks 178 andy 182 slightly beyond the hooks 177v and 181, respectively, when the' plungers are arrested by their stop screws, to permit easy `disengagement'of the'hooks. 1 y It isessential that no block 155 shall be picked or moved f to the opposite support unless the recess or boX aligned therewith is A empty. To determine thisfact, I provide a pair of detecting fingers 186 and 187 (Figs.

14 and 18). These fingersk are yieldingly mounted on a rock. shaft 188 (Fig. 14) having an arm-189 engaged by acam 190 onthe shaft 99; Offset arms 191 are fixedto the rock shaft 188 and act to swing the fingers 186 and 187away from the indicating blocks 'Y during movement thereof, such outward movementy being caused by the cam 190. The detecting linger 187 has a depending offset .projection 192 (Figs. 14 and 20) connected by a cord 193 (Fig. 14) to the hook 177 through whichthe plunger 172 is actuated to move theindicating block 155 to the left -in Fig. 14. WVhenever the detecting finger actuated to transfer an indicating block 155 to the left invFig. 14. A spring 194 moves the'finger 187 vyieldingly toward detecting position.

i Uolondcatz'on.

I will now describe the connections by which a color indication is derived from the indicator blocks 155. For this purpose an indicating arm 200. (Fig. 18) is mounted ron a fixed pivot 201 and is attached to a cord or iexible element 202. This cord 202 passes around a guide pulley 203 (F ig.,15) thence lto a second'guide pulley 204 (Fig. 1) and a third guide pulley 205 to ak rearwardly extended arm of the bell crank 108 (Fig.

1'1). This bell crank actuates the sliding rock shaftf107by which the lifting fingers 106'are moved to select a' lweft carrier of the desired color. v

The indicator arm 200I is moved yieldingly A toward. the activeindicator lblock 155, which corresponds tothe shuttle which is about to be picked rto the magazine side of the loom, by a spring 206,' until -the lowerend of the arm 200 engages the lug or projection 157 on the face of the block 155. This projec-v vtion by its height` indicates the particular shuttle to whichr it corresponds. The position of the indicating arm 200, as thus determined, acts through the cord 202 and bell crank 108 to correspondingly position the rock shaftV 107 on the magazine. The rock Q shaft will thus be moved'to correspond with y the shuttle about to be picked toward the magazine and at a time slightly prior Vt0 the actual flight of the shuttle.

The shifting shuttle boxes 13() (Fig. 9) on the .magazine end of the lay are correspondingly positioned to receive the shuttle by the operation of tivo box-positioning levers 210 and 211 (Fig. 1). Lever 211 has a pulley 212 pivot-ed thereon and lever 21() has attached thereto as at 213 a box lifting chain or cord 21d Which passes around pulley `212. Cord 21/1 is led under pulley 21d (Fig. and over pulley 214 (Fig. 14) and is secured at its other end to the arm 1113 at the' upper end of the shaft 142 (Fig. 9) previously described. The levers 210 and 211 "are rocked to correspond to thechanges indicated by the box motion chain by connections (not shown) which are old and Well hnoivn `in the art, and by their connection through the cord 21d cause corresponding movement of the shifting shuttle boxes 130 at the magazine side of Athe loom.

Box lever 300 similar to lever 210 has secured thereto as at 301 a box lifter chain 302 Which is led around pulley 303 on lever 30de, and over pulley 2305to the drop boxes 53 to which it is attached byconneetions not shown. Said levers 31)() and 804 are controlled by `pattern mechanism by connections not shown but Well understood in the art.

.lit is vessential that the indicator arm 200 be Withdrawn from engagement with the indicator blocks While the blocks are shifted either vertically orl horizontally, and for this purpose l provide a lever 216 14) pivoted at 217 and engaging the arm 200 at one end of the lever. rlhe othervend of the lever 216 engages a 218 (Fig. 16) mounted on the dobby drive shaft or box motion shaft 99. A spring 219 holds the lever 216 against cam 21S and spaced slightly `fromr lever 200 when the latter is in eni gageinent With the block 155 having the lowest boss 15T. its soon as the high point of the cam 21S is .passech the indicating arm is released to indicate the desired color to the magazine. n

iinn'iediately prior lto the movement of the vibrators 412 to their new position, the blocks are placed in accordance with their corresponding shuttles inthe supports 151 and fis the vibrators move, the supports will also move and the blocks will be in the same relative positions as the shuttles they represent will. eventually assume before picking. The block corresponding to the aetive shuttle will therefore be opposite the adjacent plunger and in positionto give ythe color indication to the magazine. For this reason the lever 20() can be moved toward the bloclras soon as desired after the vibrators stop moving.

the lay reaches front center, as the weft detector operates at this time and the color slide 107 must be placed. Said color slide and lever 200 `retain Itheir `positions until Said lever must bel `in lengagement with the active blocks when parefeu some time after the lay'has .passed `front center to permit shuttle feeler 122 to `deseend.A 1t is necessary to give the block 155 oppfsite the plunger Va movement corresponding to the movement of the active shuttle before the vibrators move again. This vcan be done any time after the lever 200 is moved away from the block. Preparatory to the movement of the block the fingers 186 and 18T are `moved to detect which block space empty .and this detection takes place before the lever v2O() is moved rearwardly. As a result of the deteetionthe proper pairof hooks are inter-locked. r1`he cam 185 :must

The parts have now completed acyclev of movements and are again ready for the next pick. will result if no block appears under lever 200 as under this condition no shuttley Will be on the drop box end ofthe loom and therefore no indication' can be given.

Operation.

Having described the details ofconstruction of the several parts of my invention,V l Will now brie'lly describe the general operat'zon thereof. the sliding support 151` (Fig.V 14) correspond in position to the shuttles then located at the magazine sideof the loom in the shuttle boxes 130, and the indicating blocks in theV sliding support 152 correspond to the positions of the shuttles then llocated at -the opposite or drop boxside of the loom.

Theblock 155 in the support 152'Which is aligned with the plunger 173 corresponds to the shuttle about to .be picked to the magazine side of the loom, this block being selected in accorda-nce 'ith'indicationsfrom the drop box pattern chain.

By the same indication, the weft detectorv 57 is moved opposite the corresponding shuttle in the drop boxes and'determines the condition of the weft supply in said No false movement of 4the maga-zinev The indicating bloc-hs 155 in f shuttle. lf the weft supply is substantially exhausted1 the detector causes the Vshaft 69 (Fig. to be rocked, thus moving an indi-. eating pin 220 (Fig. 6) into the path of an actuator 221 which normally swings about a floating pivot 222. )i7 hen the pin 220 is in the path of the actuator, the link .223 (Figs. 6 and 12) is brought .downward to release theflowermost bobbi'n B, allot these parts-beii'ig of the usual construction. Patent to Ryon, N o. 1,030,748.

The movenient of the actuator 221 isso timed that the indicated shuttle will `make vits Hight to the magazine side of the loom as the bobbin is being released and prior to the action of the transfcrrer 146 (Fig. 11).

At the saine time, the arm 72 (Fig. 2) is released to, engagev the sliding rod 75 as the lay moves back, thereby stopping the picking mechanism, the dobby, the takeup,

The movements of the indicator blocks 155 correspond exactly to the movements ofthe shuttles whichthey represent and simulate the movements of the shuttles from box to box. It is thus possible to use sevenshuttles in a 1x etV loom having eight. shuttle boxes, as it is not necessary that the same shuttle shall always occupythe same shuttle box. This free movement ot the shuttles is made possible -by the fact vthat the color indication is dependent only vupon the position of the corresponding shuttle and notL in any way upon the position of the shitting` shuttle boxes at either end ofthe lay.

The function of the indicator blocks 155 is to give an exact representation of the positionsof the different shuttles 'and to give such indication in advance of the actual movement of the shuttles so that ther color indication may be made earlier than would otherwise be possible.

Considerable time is also saved by indiiatingthe condition of wett in the shuttle about to be picked, as the drop boxes rvare moving thc shuttleY toward `picking position. The movements ot vthe blocks 155 and the detector stand 30 l'ieing indicated direct from the pattern chain, are'fsubstantially a halt pick or revolution in advance ot' the corresponding movements ot the shuttle boxes, giving ample time to indicate the color ot the running' shuttle. and to adjust the Asliding rock shaft 107 of the magazine prior to release ot a'bobbin by the ractuator 221. v

The magazine differs somewhat from the more usual type, as previously explained,

by having` a bobbin normally resting upon the releasing slide bars or supports, so that a single movement only is required to vdrop a bobbin to transfer position. When a transfer is indicated, the latch 117 (Fig. 11) `is raised into the path of the bunter 118 on the lay and is held there by the toggle arms 120 until the toggle is reversed by movement of the shuttle feeler 122 las the lay nears front center.

Aments a movement cor-respondingto every A manifest advantage ot my invention lies in the control of ythe indicating blocks and ot the drop box mechanism from the same indicating pattern surface, resulting in accurate coordination in the movements and timing` of these different mechanisms.
